Comment Re:I thought diesel ran cleaner (Score 1) 133

because it's important: exhaust gas volume is proportional to load.

Gasoline engines, yes, Diesel, no. As I posted elsewhere, Diesel engines have something closer to a fixed air intake on each revolution, irrespective of load.

Please read before replying.

Remember that Diesel engines use compression ignition and, without sufficient air, there is insufficient compression to ignite the fuel.

Would you like me to tell you about my AT185. or my OM617.951A?

Typical compression ratio in a Diesel engine is somewhere around 20:1, vs a gasoline engine that's running 10:1 or there about.

So what?

Basically this is displacement/cylinder * compression ratio * RPM * number of intake strokes per revolution.

The compression ratio is a function of the head volume and the cylinder volume. It has nothing to do whatsoever with determining how much air is drawn into the engine, which is defined by speed, bore, stroke, and intake efficiency. It is rather determined by how much air is drawn into the engine, and how much space you have left for air at the end of a compression stroke.

Ever wondered why diesel tail pipes are a lot larger than gasoline ones? This is why, diesels move a lot more air.

Diesel tail pipes are a lot larger than gasoline ones because diesels shit the bed when you have backpressure. It ruins their efficiency and you have to play tricks to get it back. Turbocharging is worth it anyway because it's turbocharging. Now, pay attention to this part, because it's important: exhaust gas volume is proportional to load. Diesels have bigger exhausts because they have more torque. This is also why turbochargers and diesels go together so well. Turbochargers are driven by exhaust gas expansion, which as mentioned, is proportional to load.

If you carve the piston out, you lower the compression ratio, and you increase the amount of air the engine consumes. You in fact have this exactly backwards.

Not when cruising at 65 mph. Not even close.

Well, tell us what it is. Neither of my turbos boost that high, but they're both old. (My F250 peaks out at 11 psi and my Mercedes at 12.) The F250 cruises at only around 2 psi unless you have a trailer, then it's more like 6 or 7. The Mercedes cruises at around 7 or 8 psi. But they have much lower boost pressure than modern diesels.

And still has a hell of a lot of particulate emissions, negatively impacting air quality in major cities, which you might note are the entities banning the diesels here.

Gasoline has just as much particulate emissions as diesel. It's just a smaller soot particle which we couldn't accurately measure until recently. Of course, DPFs on diesels reburn the soot until it's a small, invisible particle just like gasoline, making it just as dangerous as gasoline.

Banning diesel is not the remedy. Banning combustion is the remedy. Banning diesel is just stupid.

They're all going to agree to never lobby for foreign entities, and go half a decade after they leave office before they can do that work domestically.

Guess what? Those agreements are unconstitutional and won't stand. That's like a Californian signing a non-compete agreement. Okay! Sure!

While I agree with everything you've said, you're making false equivalences... One (huge) mistake doesn't turn a legit news organization into a supermarket tabloid, just as a few lies on one side doesn't balance out a voluminous blatant and continuous intentional disinformation campaign on the other side.

THAT is a perfectly valid reason why discussion on the topic tends to be one-sided, even if problems on the other side need to be resolved as well.

Comment Re:So much for public charging locations (Score 2) 153

Should be trivial to construct a USB charging cable with inline fuses (or sacrificial caps/resistors/diodes), maybe adding $1 to the cost of the cable, and protecting your expensive devices from not just intentional sabotage, but also cheap, poorly engineered chargers, which might just kill you.

It was already bad hygiene to plug-in a USB cable that has the data lines intact into a public port, as all your data could be quietly siphoned off, and malware loaded on. If this new threat gets people to pay attention to previous threats, we might all be better off for it.

Incidentally, Friedman also supported the most reasonable solution to the problem we'll be facing - a universal basic income.

And exactly where does this *magic* money come from to pay out all this Universal Basic Income?

If hardly anyone is working where does this magic money come from?

Are you going to take the few people making a LOT of money 3/4's or more of their income to give handouts to everyone else?

At some point, people get pissed they're working for something, and all their money and incentive to work is taken away.

Hell, if you took and confiscated EVERYTHING the top 1% currently owns...it would not pay the rest of us anything for even a full year. What do you do after that?

I grew up as a kid in the 60's and 70's and 80's....

I saw the rise of the internet from nothing till now.

And honeslty, I"d seriously consider trading some of the tech we have today, to go back to have more closeness and civility we had back then.

I actually am starting to thinks that some of the all the time connected social media proliferation, has had somewhat of a detrimental effect on our society.

We're certainly MUCH more polarized as a nation now than then....I'd trade a few smart phones for that again.

I'm certainly glad I'm not growing up a kid today....

If Hillary got elected, it would have been business as usual and things would have continued on as they have under Obama.

You say that as almost if you think that was a good thing.....?!!?

Obama..worst president to date, just barely undercutting the previous Bush.

Again, I'm not a huge Trump supporter by a long shot. I don't think he's all that knowledgeable, but I do think he knows how to gather people around him that do.

I was actually this time around...and I hate to admit it...a single issue voter.

The Supreme Court.....and next nominees to it. That was what scared the piss out of me about Hillary even more than all the other stuff I didn't like about her and the potential for continuing Obama.

I think "O" led the US fully down the wrong road, and tried to fundamentally change what it meant to be the US and to be a US citizen. He was a globalist and often I wondered if he thought of the US first when it came to things, or if he was how will this affect the world all the time.

I'm not hiring my leaders and my government to think about how we can better the world to the detriment of the US, but I want them there to fight to compete the best we can with the rest of the world.

Certainly the rest of the world is thinking about themselves first too....and we need to do the same, or lose.
